From the pictures, I would have to say no, but you have it in hand; I have a tough time photgraphing FBL examples in slabs so I would not rule it out. I am on my iPad and the pictures suggest proof - if that is the case, I do not believe it would be graded with the FBL designation as I believe that FBL is reserved for business strikes only (but there are proofs without the continuous lines on the bell also). Someone please correct me if that is inaccurate.
Now, how "bout a picture of the obverse!
